Considering its a 5 watt max Laser Ionics with a quartz tube, and they need shipped in a air ride electronics van because of the exposed glass resivoirs tubes on the bottom of the base, that one is a non starter for anything other then local pickup.

Its a tungsten disk tube, it does have that going for it, and it most likely has a built in pressure pump if its like most Laser Ionics lasers.

You actually have a good chance of it starting. They may have been designed for low cost and short life, but a lot of them stay working at about 1/3rd rated power for decades.

The gas reservoir looks like it has a spent getter - is it something else? If it is indeed a getter I'd stay far away from it let alone pay five grand for it.

(white residue in pic 8)

Thats not a getter, that is cathode processing residue, the getter is elsewhere on the tube. I agree with you, no more the 100$ if you dont see it run, and no more the 400$ if you do. You can do so much better with a Coherent or SP or ALC product.
